This paper presents the implementation of optimization technique on the HEMS (Home Energy Management System). The objective of load scheduling optimization problem is to minimize the peak hourly load power consumption. The Raspberry Pi module is employed as the smart controller installed at a home. The smart controller is used to solve the optimization problem using MILP (Mixed Integer Linear Programming)...
This paper presents the fusion techniques for detecting and tracking the face. The proposed method combines the Viola-Jones method, the CamShift tracking, and the Kalman Filter tracking. The objective is to increase the face detection rate, while reduce the computation cost. The proposed method is implemented on a low cost embedded system based-on the Raspberry Pi module. The experimental results...
This paper presents the development of PV (photovoltaic) simulator used for laboratory testing. The proposed simulator integrates both the software and the hardware devices. The aim of the proposed simulator is to develop an instrument that provides the output electrical power which is determined by the characteristic of PV under the varying solar irradiation. The Simulink software is employed to...
This paper presents an application of the Raspberry Pi for detecting laser spot using the OpenCV library. To capture the image, a Web-Camera connected to the USB port of the Raspberry Pi is employed. Since the Raspberry Pi is small in size, the module could be mounted on the gun for laser shooting. Compared to the existing laser shooting, our method has benefit in the flexibility of laser shooting...
This paper presents the implementation of an embedded camera system applied for shooting training, where the sensor on the gun system is adopted. A CMUcam4 is attached on the gun to detect the laser spot emitted by the shooter. In addition, the camera is used to detect the coordinates of marker on the target, which are sent to a computer for calculating the homography transform. A simple color thressholding...
This paper presents the camera-based shooting simulator, where the shooter shots the target using a laser pointer attached on the weapon. A camera is attached on the weapon to capture the image of laser shot and circular target. The red color thresholding techniques are employed for detecting the laser spot on the target. From the experiments, it is obtained that the proposed system could detect both...
In this paper, the data acquisition system is developed to monitor the wind speed, solar irradiation, and PV temperature based on a low-cost AVR microcontroller. Instead of using an expensive pyranometer, a low-cost PV module is used as the solar irradiation sensor. The integrated-circuit temperature sensor LM35 and a cup-type anemometer are used to measure the temperature and the wind speed respectively...
This paper presents the modeling of wind energy systems using MATLAB Simulink. The model considers the MPPT (Maximum Power Point Tracking) technique to track the maximum power that could be extracted from the wind energy, due the non-linear characteristic of the wind turbine. The model consists of wind generation model, converter model (DC-DC converter), and MPPT controller. The main contribution...
In this paper, the development of a cost-effective shooting simulator is presented. The proposed system employs the photodiode sensors for detecting the laser pointer. To reduce the cost, the photodiode sensors are arranged into rows and columns, and the scanning technique is adopted to detect the presence of the laser beam on the sensor arrays. A cheap microcontroller system AT89S52 is used to perform...
